# Exploring other dimensions

This is a very interesting video about the world of dimensions.

Imagine a two-dimensional world — you, your friends, everything is 2D. In his 1884 novella, Edwin Abbott invented this world and called it Flatland.

Alex Rosenthal and George Zaidan take the premise of Flatland one dimension further, imploring us to consider how we would see dimensions different from our own and why the exploration just may be worth it.

# Da Vinci’s Vitruvian Man of Math

An interesting view into Da Vinci’s Vitruvian man.

What’s so special about Leonard da Vinci’s Vitruvian Man? With arms outstretched, the man fills the irreconcilable spaces of a circle and a square — symbolizing the Renaissance-era belief in the mutable nature of humankind.

James Earle explains the geometric, religious and philosophical significance of this deceptively simple drawing.

# The infinite life of pi

This is a video about the number PI.

The ratio of a circle’s circumference to its diameter is always the same: 3.14159… and on and on (literally!) forever. This irrational number, pi, has an infinite number of digits, so we’ll never figure out its exact value no matter how close we seem to get.

Reynaldo Lopes explains pi’s vast applications to the study of music, financial models, and even the density of the universe.

# Is Math a Feature of the Universe or a Feature of Human Creation?

This video answers an interesting question :does mathematics exists without humans?

Math is invisible. Unlike physics, chemistry, and biology we can’t see it, smell it, or even directly observe it in the universe. And so that has made a lot of really smart people ask, does it actually even EXIST?!?!

Similar to the tree falling in the forest, there are people who believe that if no person existed to count, math wouldn’t be around . .at ALL!!!! But is this true? Do we live in a mathless universe? Or if math is a real entity that exists, are there formulas and mathematical concepts out there in the universe that are undiscovered? Or is it all fiction? Whew!! So many questions, so many theories… watch the episode and let us know what you think!

# The Mathematics of History

Can mathematics be used to understand history ?

What can mathematics say about history?

According to TED Fellow Jean-Baptiste Michel, quite a lot. From changes to language to the deadliness of wars, he shows how digitized history is just starting to reveal deep underlying patterns.

# The Magic of Vedic Math

This video show an interesting and simple way to do math using Vedic math.

There is more than one way to reach a correct answer in mathematics. Vedic math, an ancient Indian method, sidesteps traditional computations in a manner that provides a shortcut, while being fun to use and to learn. At TEDYouth 2012, to ooh’s and aah’s from the amazed crowd, Gaurav Tekriwal demonstrates the magic of Vedic math.

# What is Zeno’s Dichotomy Paradox?

An interesting video from TedEd about Zeno’s Paradox and mathematical series.

Can you ever truly get from Point A to Point B? According to Ancient Greek philosopher Zeno of Alea, yes, you can — but it’s complicated. How can infinitely divisible numbers equal a finite sum?

Colm Kelleher illustrates how to resolve Zeno’s Dichotomy Paradox.

# Who controls the world?

This is an interesting video about finance, economy and our modern society in the context of the science of complexity.

James Glattfelder studies complexity: how an interconnected system — say, a swarm of birds — is more than the sum of its parts. And complexity theory, it turns out, can reveal a lot about how the economy works. Glattfelder shares a groundbreaking study of how control flows through the global economy, and how concentration of power in the hands of a shockingly small number leaves us all vulnerable. (Filmed at TEDxZurich.)

# How Maths Illuminates Our Lives

An interesting video about the love of mathematics and it’s place in our reality from RSA.

Acclaimed author and one of the world’s most extraordinary minds, Daniel Tammet visits the RSA to give us a unique perspective on how mathematics can help us to make sense of the world and our place in it.

More informations are found on the event page :

How does mathematics shape our lives and give our experiences meaning? Can mathematical modelling predict human behaviour, and how can equations help us to make sense of the people we love?

Acclaimed author of Born on a Blue Day, Daniel Tammet is hailed the world over for his extraordinary mind and unique intelligence. A high-functioning autistic savant and synaesthete, Tammet perceives words and numbers as shapes, colours, and emotions, and holds the European record for reciting the mathematical constant Pi to 22,514 decimal places.

Daniel Tammetvisits the RSA to give us a unique glimpse at the extraordinary and misunderstood language that governs our world, and to explain the infinite mathematical possibilities that surround us.

# The beautiful math of coral

How can we visualize the power of mathematics ?

Science writer Margaret Wertheim re-creates the creatures of the coral reefs using a technique invented by a mathematician — simultaneously celebrating the amazements of the reef and deep-diving into the hyperbolic underpinnings of coral creation.
